See Table 4 for information about our use of non-GAAP measures and definitions of OIBDA and free cash flow, and Table 5 for footnotes.

TABLE 4Use of Non-GAAP Financial Measures

“OIBDA,” “Adjusted OIBDA,” “cash interest expense” and “free cash flow” are not financial measures calculated in accordance with generally accepted accounting principles (“GAAP”) in the United States. We define OIBDA as operating income before depreciation and amortization and Adjusted OIBDA as OIBDA plus investment income from affiliate. OIBDA and Adjusted OIBDA may not be comparable to similarly titled measures used by other companies, which may have different depreciation and amortization policies, and are key components in our covenant calculations.

We define cash interest expense as interest expense, net, less amortization of deferred financing costs. Cash interest expense excludes the amortization of financing costs which were paid upon the financing of the relevant debt.

For Mediacom Broadband LLC, we define free cash flow as OIBDA less capital expenditures, cash interest expense and dividends to preferred members. For Mediacom LLC, we define free cash flow as Adjusted OIBDA less capital expenditures and cash interest expense. Free cash flow may not be comparable to similarly titled measures reported by other companies.
